I read this comprehensive review before purchase and you should too:http://www.imaging-resource.com/PRODS/canon-eos-m/canon-eos-mA.HTMI'm an amatuer photog for more than 40 years. Until recently, my only concession to digital photography was the purchase of inexpensive Canon point-n-shoots. As film photography has become a greater burden and digital has caught up in terms of quality while surpassing in convenience and affordability, my discovery of this little gem at a bargain price was perfect timing. Adding a $15 adapter, I can use may ancient but excellent FD mount Canon lenses - think F1 and AE-1 cameras. Auto-focus speed doesn't matter to me because I still prefer to manually set almost everything. That said, the AF performance of the EOS M seems equivalent to that of my son's Nikon 1.My purchases for my entry into serious digital photography to date include: the EOS M with Speedlite 90EX and EOS M 18-55mm IS lense: an SD card (PNY 64 GB High Speed SDXC Class 10): a spare battery (Opteka LP-E12 LPE12 2000mAh Battery Pack): a lense adapter (Fotasy Canon FD Lens to EOS M Lens); and a neck strap (OP/TECH USA System Connector Super Pro A).

I purchased this adapter along with the EOS M camera kit to use with my EF and EF-S lenses. After less than a week, I have been able to try out with the EF 50mm F1.4, EF 70-300mm L, EF-S 17-85mm, and EF-S 60mm lenses. The adapter fits perfectly. Same form and fit as the Canon extenders I have. The EOS M is of course made very tiny with any large EF lens. It creates a sort of 'pocket Rebel'. Of course, once you mate with the larger lens, this is no longer going to fit in anything less than a massive coat pocket. The combination of camera, adapter, and lens seems comfortable after brief handling. The EF 50mm was a very comfortable combination, the adapter does not add a very large amount to the overall combination. The upside to this adapter is if you already have a variety of EF and/or EF-S lenses. The image quality of the JPEGs, right out of the camera ranged from expected to stunning (the latter results obtainable with off camera studio flash strobe and soft box). The adapter was immediately a huge part of the EOS M camera purchase. I highly recommend it if you have other lenses. Again, the results I got with the EF-S 60mm macro (and studio lighting) were stunning. It transformed the camera from curiosity to studio prime. No problem using manual mode and Pocket Wizard. Include this adapter in your purchase and you won't be looking back.

I do a tremendous amount of photography and am an old Leica user. It takes a lot to get me excited. When this digicam came down in price- I bought it. I have been using m43 and have a great deal invested in that size. Because of the weight- I have rarely used my Canon DSLR. I also do street photography so I need a fast camera. The EOS M is NOT a fast camera. The imaging, however, is spectacular. Notwithstanding the latest articles in magazines and on line, APS C is much better than m43.I use it with an optical v/f I also bought on Amazon. I shoot black and white and although the camera's color rendition is excellent, the black and white is so spectacular that I went specifically to this site to crow about it. I am waiting now with bated breath until a new EOS M is released with an integral EVF. If you get used to the focus lag... shoot with "continuous" your results, like mine will be worth the trouble.

Rented this from lens rentals, loved it and I’m buying it. Best pictures I have taken with my EOS R in the 14 months I’ve owned it.

This lens adapter fits my new canon eos M50 to my Tamron and irix and sigma lenses that I got before this camera. They all fit ef-s mount for the rebel t6 camera

So you finally decided on getting the EOS M (it's flaws considered). I assume you are a canon user, have a couple of good (canon EF/EF-S mount) lens lying around and would like to be able to use those on you EOS M. Just like me, you love your canon dslr but sometimes wish you can travel light but still be able to enjoy the canon ecosystem that you have grown to love. If you are what I assume you are, get this lens adapter.I took a gamble and bought a "like-new" used from a seller at Amazon and was very happy with a purchase. For anything more than $150 I probably would think twice. But I am not taking a start out because of the price. This adapter handles every canon mount lens I threw at it. The build quality is nice. The design (the way it attaches to the eos m; the included, detachable tripod mount) is well thought of... just perfect.

I am using this lens for Canon M50 Camera. You will need EOS adapter. I have attached 3 photos taken with this lens.

As a Canon DSLR shooter this adapter is a must for owning the EOS M. It's really the only reason why I bought the EOS M. I love the 22mm f2 that comes with it, but being able to use my nearly $10k worth of lens on this makes it a steal. I believe without this adapter the camera is very limited. The adapter fits the camera and lens nicely. I personally feel that the lense attaching to the EOS M feels strange, tight compared to all my DSLRs, but this adapter and lens are snug once attached, and that's what matters.
